The study found that farming and food alone, which accounts for a third of all greenhouse gasses, would be enough to heat the world by more than 1.5°C by the 2060s.

Michael Clark, researcher at the Oxford Martin school and lead author of the study, said, “There needs to be more focus and more effort to reduce emissions from the food system. Greenhouse gas emissions from food systems have increased due to a combination of dietary changes – more food in general, with a larger proportion of food coming from animal source foods – population size and how food is produced.”
